I still remember the very first time I made Japanese Potato Salad. It was one of those chilly, rainy Sundays when I craved something comforting yet light, and this salad just hit the spot perfectly. The moment I started peeling the potatoes and smelled the warm steam mixing with the tangy scent of Japanese mayo, I knew it was going to be a family favorite. We’ve all had those moments where a simple side dish turns into a treasure trove of good memories—and Japanese Potato Salad definitely did that for us. The creamy potato mash paired with crisp cucumber slices and the slight crunch of carrot julienne always makes me smile every time I scoop it onto our plates.
Japanese Potato Salad wasn’t always my go-to. I’ll admit, I’ve faced my share of kitchen mishaps trying to get the textures just right—overcooked potatoes turning into a soggy mess and the dreaded flavor imbalance from too much mayo. It took a bit of trial and error, but once I found the perfect balance of softness in the potato mash and freshness from the veggies, plus a touch of homemade egg salad folded in for that extra richness, it quickly became a staple in our dinner rotation. What really seals the deal for me is the use of authentic Japanese mayo, which adds a slightly sweet and creamy tang that’s so different from regular mayo.
Fitting this dish into my busy family life has been a blessing. It’s quick to whip up on hectic weeknights or great to prepare ahead for gatherings. The versatility means I can adjust ingredients based on what’s in the fridge, and everyone always loves it—kids too! If you’re glancing at this recipe feeling a bit intimidated, you’re not alone—I was there too. But I promise, once you get to know this Japanese Potato Salad, it’s kinda like having a secret weapon in your meal arsenal. Plus, if you’re curious about different versions, I found some lovely takes shared by others online, like the Japanese mac salad with kewpie mayo which inspired me to tweak mine. Have a cup of tea, and I’ll walk you through everything I’ve learned about making a truly delicious Japanese Potato Salad that your family will adore.
Ingredients:

- 3 large potatoes (about 1.5 pounds) – I always use starchy potatoes for my Japanese Potato Salad because they mash easily yet hold some texture.
- 1 small cucumber – thinly sliced for crisp cucumber slices.
- 1 medium carrot – cut into fine carrot julienne strips.
- 2 hard-boiled eggs – mashed into creamy egg salad bits.
- 1/2 small onion – thinly sliced and soaked in cold water to tame the sharpness.
- 1/2 cup Japanese mayo (like Kewpie) – this is a must-have for authentic flavor.
- 1 teaspoon rice vinegar – adds a slight tang and brightness.
- Salt and pepper – to taste.
- Optional: 1 tablespoon sugar – for a subtle sweetness that balances the salad.
I like to keep things simple yet flavorful when making Japanese Potato Salad, so these ingredients work perfectly for me. You can grab Japanese mayo at most Asian grocery stores or even online; it’s the key to that rich, slightly sweet taste that sets this salad apart. If you’re ever wondering about ingredient prep shortcuts, I’ve found that boiling the potatoes in chunks helps them cook evenly and mash nicely without turning into watery potato mash. Plus, soaking cucumber slices a bit in salted water reduces some moisture so your salad doesn’t get soggy.
When making Japanese Potato Salad, you might want to peek at some ingredient tips over at My Pinterventures’ Vegetable Potato Salad Recipe – Japanese Potato Salad for some creative vegetable twists. I also keep my carrot julienne ready in a container, so tossing together the salad after work is less of a chore. For budget-friendly ideas, seasonal vegetables work wonders here—adding crunchy radish or even bell pepper can swap in nicely without breaking the bank. Leftovers? I store any extra potato mash or boiled eggs separately so everything stays fresh until I mix it all together again.
How to make – Step-by-step:
- Prepare the potatoes: Peel and cut into roughly equal chunks. Boil them in salted water until tender but still holding shape — usually about 15 minutes. I learned the hard way that over-boiling makes the potato mash too watery for Japanese Potato Salad, so keep an eye on that! While the potatoes are cooking, I like to move on to prepping the veggies.
- Slice the cucumber and carrot: Thin cucumber slices and fine carrot julienne give the salad that fresh crunch. I sometimes soak the cucumber slices in salted water for about 10 minutes to keep them crisp and prevent excess moisture from ruining the texture.
- Prepare onion and eggs: Thinly slice the onion and soak it briefly in cold water to soften its bite. Peel hard-boiled eggs and mash them roughly to create a creamy egg salad texture blended right into the salad.
- Make the dressing: In a bowl, combine the Japanese mayo with rice vinegar, salt, pepper, and optional sugar. The rice vinegar is subtle but gives the dressing a bright lift. I like to taste as I go, adding a little more mayo or vinegar depending on how creamy or tangy I want the Japanese Potato Salad.
- Mash the potatoes: Drain the potatoes and let them cool slightly, then gently mash them. You’re aiming for a soft potato mash that’s still a little chunky—not too smooth or pasty. This is key for authentic Japanese Potato Salad texture.
- Combine everything: Fold in the cucumber slices, carrot julienne, onion, and egg salad bits into the mashed potatoes. Pour over your mayo dressing and mix gently but thoroughly.
- Chill before serving: I always refrigerate the Japanese Potato Salad for at least an hour. It lets the flavors meld, and your Japanese Potato Salad will smell delightfully fresh and inviting.
In my kitchen, making Japanese Potato Salad usually takes about 40 minutes from start to finish — perfect for a weekend lunch or quick dinner side. While the salad chills, I often prepare main dishes or tidy up the kitchen.

Serving:

The best part about Japanese Potato Salad is how much my family loves it whether as a side or a light meal. The kids especially ask for extra cucumber slices, which add just the right crunch. We usually serve this salad alongside grilled chicken or fish, which balances the creamy and fresh flavors beautifully. If you’re looking for pairing ideas, I highly recommend trying it with other potato-based salads like potato and green bean salad or even mix it up with baked potato salad for more texture fun.
Some of my favorite occasions to make Japanese Potato Salad include casual family get-togethers, picnic days, or even holiday dinners where it can act as a refreshing contrast to richer mains. Presentation-wise, I love topping the salad with a sprinkle of black sesame seeds or some thinly sliced nori strips for a little extra umami flair. Leftovers can be quite versatile; if you happen to have extra Japanese Potato Salad, mixing it into sandwiches or serving it atop fresh greens for lunch tastes just as wonderful the next day.
One surprise I’ve discovered is making seasonal twists by adding a bit of roasted sweet potato or swapping carrots for radish, which adds a nice peppery bite without losing that classic vibe. Friends who have tried my recipe always come back asking for more, and it’s even prompted them to make their own versions inspired by this dish’s simple ingredients and customizable nature.
FAQs:
1. Can I make Japanese Potato Salad ahead of time?
Oh absolutely! I love making it the day before because the flavors mellow and really come together overnight. Just keep it chilled tightly covered. I’ve found that making it in advance actually improves the taste.
2. What’s the best potato to use for Japanese Potato Salad?
For me, starchy potatoes like russets or yukon golds work best. They mash smoothly but still hold little lumps, which is the texture we’re after. Waxy potatoes tend to get too gluey if overworked. If you want to compare with other potato salad styles, check out this German potato salad for how different potato types affect texture!
3. Why do some Japanese Potato Salad recipes use Japanese mayo instead of regular mayo?
Japanese mayo is silkier and has a bit of brightness with slight sweetness thanks to rice vinegar, which regular mayo doesn’t offer. It’s a subtle but important difference that really elevates the flavor of the whole salad.
4. How thin should I slice the cucumber for the salad?
Just think thin but not paper-thin. I slice mine about 1/8 inch thick which keeps a satisfying crunch. Sometimes I salt and soak the slices briefly to draw out excess water, keeping the salad from getting watery.
5. Can I omit the carrots or egg salad in the Japanese Potato Salad?
Sure, though those bring texture and extra flavor. My family would definitely miss the mild sweetness and crunch carrot julienne offers, plus the creamy richness from the chopped egg salad is another layer that makes the salad so comforting.
6. How do I avoid watery Japanese Potato Salad?
This was a struggle for me at first. The trick is not to overcook potatoes and drain cucumber slices well after soaking. Also, fold the ingredients gently to avoid breaking down the potato mash further.
7. Any tips for making Japanese Potato Salad kid-friendly?
Definitely add extra egg salad bits or even corn kernels for a touch of sweetness. Japanese mayo is a hit with kids too because it’s less tangy than regular mayo. My youngest always asks for more carrot julienne too!
